The Inverto 18X was not a full staking tool set. Rather, it was a friction jeweling attachment for a customer's existing frame and a set of friction jeweling accessories.
The 18X came in three configurations, depending on what type of frame the customer owned: Older Inverto 18 frame: 18X with No. 540 attachment Older Inverto 18B frame: 18X with No. 540R attachment Newer Inverto 18B frame: 18X with No. 540S attachment Only the No. 540S was owner-installable in the field. For the No. 540 and No. 540R, the frame had to be returned to K&D for factory installation of the jeweling attachment |
